SYSTEM AND METHOD FOR DYNAMICALLY REGULATING QUALITY OF PARTIAL POWER GRID FOR HOUSEHOLD ENERGY STORAGE SYSTEM

摘要

Disclosed in the present invention is a system for dynamically regulating the quality of a partial power grid for a household energy storage system, comprising an energy management system, a grid-connected inverter and a wireless power grid dispatching device, wherein the wireless power grid dispatching device wirelessly acquires real-time power grid quality information of a power grid company, and sends the acquired power grid quality information to an energy management system; the energy management system carries out analysis and calculations according to the fed back power grid quality information in combination with a preset standard threshold to obtain power grid frequency and voltage fluctuation range values; and the grid-connected inverter, as an execution unit, outputs active electric energy or reactive electric energy to the power grid to regulate.
